A male elephant seal can have as many as 50 females in his harem. Habitat Northern elephant seals live in the North Pacific near Baja California, Mexico to the Aleutian Islands and the Gulf of Alaska. Southern elephant seals live in the sub-Antarctic and Antarctic waters.These seals migrate ...
The park offers guided walks lead by volunteer docent naturalist to see the northern elephant seals in their natural habitat inside the Año Nuevo Coast Natural Preserve. Año Nuevo docents go through extensive training and are highly knowledgeable in the natural and cultural history of the park....
One of the largest carnivores (食肉动物) is the southern elephant seal. It can reach 7 metres in length and weigh 5,000kg! That's five times heavier than a polar bear! Much of its weight is from huge layers of fat, which are needed to keep it warm. Its habitat is the southern par...
But the largest concentration of Southern elephant seals, over half of the entire population, is found in South Georgia. Their habitat, when not in the ocean, is the rocky and sandy beaches where it mates and gives birth.The Southern elephant seal has few predators. The orca and the grea...

Oceanographic parameters other than the ones considered in our analyses are also likely to affect prey distribution and foraging habitat, such as chlorophyll density, which is linked to primary production (Moore and Abbott, 2000), salinity, a key physical parameter of oceans (Caldwell, 1974), or...
Southern elephant seal life cycle Southern elephant seals are wide-ranging marine predators that haul out on land to breed and moult. Every September to October, pregnant females (age three and older) haul out to give birth to a single pup. Female seals do not forage during the breeding seas...
elephant seal pup mortality rose to 80%. El Niño events cause severe winter storms, elevated sea levels, heavy rains and high tides that can submerge colonies and wash away pups. It is known that the Farallon Islands colony decreased by nearly half due to habitat changes caused by winter ...
